LIQUID DISPENSING DEVICE Fild sept. 2e. 4192s Y 3 sheets-sheet s S14/vento@ /I alitomw/to Patented June 3, 11930 HARRY K. PRATT, OF LONG- BEACH, NEW YORK LIQUID-DISPENSING DEVICE Application led September 26, 1928. Serial No. 308,379.

The present invention is directed to improvements in liquid dispensing devices.

. The primary object of the invention is to provide. a device of this character so con-` structed that the liquid will be attractively displayed and can be dispensed in measured quantities.

Another object of the invention is tn provided a device of this character so construct- ?.e ed that air under pressure will be alternately conducted to the measuring tank and -exhausted therefrom, the inlet and exhaust of the air being controlled by the weight of the Adischarge hose.

Another object-of the invention is to providea device of this character so constructed that thev quantity of liquid dispensed will be registered.

With these and other objects in' view, this invention resides in the novel features of con- 1 struction, formation, combination and arrangement of arts to be hereinafter more fully describe claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side view of the pump showing the storage tank associated therewith.

Figure 2 is a vertical sectional view. Figure 3 is a sectional view on the line 3-3 of Figure 2.

so Figure 4 is a detail view, partly in section, of the registering assembly.

Figure 5 is a sectional view on the line 5-5 of Figure 4. Y

. Figure 6 is a detail view of onev of the valve and pipe connections.

Figure 7 is a detail view ofthe hose sup'- ort.

P Figure 8 is a fragmentary plan view of the hose support,the valve being shown in Van section.

Referring to the drawings, 1 designates a hollow supporting base of conventional shape and provided with a top plate 2, said plate having seated thereon liquid receiving Nvessels 4f' 3, 4, 5, and 6, formed of clear glass and rectangular in cross section. The lower edges of the vessels are seated in packed grooves 7 formed in said plate. y ranged in pairs and between which is mount- 50 ed a measuring tank 8, also of clear glass, said The vessels are are.

tank being elongated and extending from end to end of each pair of vessels. The tank 8 is approximately half the height of said ves- 'sels in order to provide a chamber 9, the pur- -pose of which will later appear. The vessels and the tank are maintained air-tight by clear glass covers 1Q.

The vessels 3, 4, 5, and 6 communicate with the tank 8 through pipes 11, 12, 13 and 14, respectively. each pipe having avalve 15 therein provided with a spring operating lever 16, the purpose of which will be later explained. These pipes vextend under the plate 2 and have their upper ends fixed to said plate in a manner to prevent leakage.

The liquid storage tanks 17, 18, 19 and 20 are located near the base 1, air under pressure being furnished t-o the tanks through a pipe assembly 21 leading from a source of compressed air, as is customary in devices of this kind.

. The tank 17 is connected with the vessel 5 by a supply pipe 22 while the tank 18 supplies the vessel 3 through a pipe 22. Connecting the tanks 19 and 2O with the vessels 4 and 6 are supply pipes 24 and 25.

Extending into the tank 8 are pipes 26 and 27 provided with valves 28 and 29, re-

- spectively,said valves being preferably of the turning plug type. These valves are connectedby a common stem 30 so arranged thatwhen one is open the other will be closed.

`The pipe 27 has its valve casing connected to the compressed air conducting pipe-31' which is connected in the pipe assembly 21, 85 while the pipe 26 opens to atmosphere.

The stem 30 has fixed thereto a pair of bars 32, one of the ends thereof having hooks 33, while the other end is equipped with counterweights 34 to counterbalance the weight 90 of the filling nozzle 35 of the hose 36, said hose being connected to the discharge pipe 37 which leadsfromthe tank 8. It is through this hose'and nozzle that the contents of the tank 8, in measured quantities, is' dis- 95 pensed. ,Y

-Supported by and depending from the plate 2 is a casing 38 in which is supported a Iguide 39, and slidable in the guide is a rack bar 40 having engagement with the 100 toothed wheel 41 carried by the inner end of the shaft 42, which extends through a stuffing box 43 of the casing and connects with a register 44 of any well known type. To the i outer ends extended from the support 1 in order that they may be -pushed inwardly to operate the valves 15 to permit liquid to pass through the pipes into the tank 8. Since the liquid in the vessels is under pressure from the compressed air entering the storage tank, the liquid will flow when the valves are opened into the tank 8. The vessels are preferably of a size to contain a gallon of liquid so that when the liquid is transferred from one vessel into the tank 8 to refill the same after the contents thereof have been dispensed through the hose 36. It will, of course, be understood that the capacity of the vessels can be varied if desired.

A top 47 is supported by the vessels and may be ornamented to suit the fancy of the manufacturer. An incandescent bulb 48 is arranged in the chamber 9 in order to supply heat in cold weather to maintain the contents of the vessels at a flowing temperature. The bulb also serves to illuminate the contents of the various vessels and, if desired, the contacting faces of the vessels may be painted white in order that the contents thereofwill be more effectively displayed.

While I have illustrated the device as employing four receiving vessels, it will, of course, be understood that two of such vessels may be used in connection'with the tank, 4or if desired, the number may be increased to more than four as illustrated. Y

When the hose is lifted from the hook A33, the arm 32 will swing under the action of theweights 34, thus opening the valve 29 to permit air under pressure to enter the tank 8 through the pipe 27 for forcing the liquid therefrom through the hose. When the hose is replaced upon the hook the valvel 2.9 will close and the valve 28 will open, thus permitting the residue air in the tank to escape through the pipe 26 to atmosphere to prevent back pressure when the valve 29 is again opened.

When it is desired to transfer the contents of each of the vessels to the tank 8, it is only necessary to press inwardly upon a selected rod 46 to open a valve 15. In this manner, the liquid can be conveniently dispensed in measured quantities.

' The device is primarilyl designed for dispensing lubricating oils of various grades but it will be, of course, understood that it can be successfully used for dispensing liquids other than oil.

Having thus described the invention, what I claim is:

1. A liquid dispensing device comprising a plurality of liquid receiving vessels, a measuring tank disposed between the vessels, valve 'the pipe, a pipe for conducting compressed air to the tank, a pipe for exhausting residue air from the tank, a valve in each of said pipes, means for supporting the hose, the hose supporting means being operable to open one valve when the hose is removed from the supporting means to admit air through one pipe to the tank, and to close the same and open the valve of the other pipe when engaged upon the hose supporting means to exhaust residue air from the tank.

3. A liquid dispensing device comprising a base, a plurality of liquid receiving vessels mounted thereon, a measuring tank mounted between the vessels, pipes connecting thevessels with 'the taukgvalves in the pipes, rods pivotally connected with the valves and slidably supported by the base, said rodsk being selectively operable for controlling the now of liquid from the vessels through the pipes to the tank.

4. A liquid dispensing device comprising a base, a plurality of transparent liquid receiving vessels mounted thereon, a transparent tank supported by the base and disposed between the vessels, means for'conducting fluid to the vessels, means for transferring fluid from a selected vessel into the tank, said vessels and tank defining a chamber, and an illuminating elementV in the chamber for illuminating the contents of the vessels and tank. Y

' 5. A liquid dispensing device comprising a plurality of liquid receiving vessels, a tank disposed between the vessels, valve controlled means for controlling the flow of liquid from -the vessels into the tank, a discharge pipe leading from the tank, a hose connected with the pipe, means for conducting compressed air to the tank and exhausting residue' air therefrom, and means controlled by the weight of the hose for controlling the admission ofair. to the tank and the exhaust of residue air therefrom..

In testimony whereof I afiix my signature.
